Faild to add vlan filter to a vf used dpdk

HI

I set 4000-4049 vlan filter to a vf:

for(vlanindex = 4000;vlanindex<=4049;vlanindex++)

        {

            diag = rte_eth_dev_vlan_filter(dev->port_id,vlanindex,1);

            if (diag) {

                VLOG_INFO("Interface %s vlan(%d) setup error: %s",

                          dev->up.name, vlanindex, rte_strerror(-diag));

                return diag;

            }

        }
